AI Technical Summary
Technical Problem
In automotive environments, sharing storage among multiple applications is inefficient due to cost and space constraints, and existing area allocation methods fail to allocate space effectively when the unallocated area does not meet the requested capacity.
Method used
An electronic control device that includes an area allocation method and program to release unused space from already allocated applications, prioritizing those with low access frequency or remaining usage period, to combine with unallocated space and allocate to new requests.
Benefits of technology
Effectively allocates storage space by releasing unused space from low-access or low-usage applications, ensuring sufficient space is available for new requests without impacting existing applications.

Abstract
To appropriately allocate the allocation area of an area reservation request application when an area reservation request from the area reservation request application is accepted and the capacity of unallocated areas of a storage does not exceed the required capacity.SOLUTION: An electronic control device 1 comprises: an area reservation request acceptance unit 2a that accepts an area reservation request from an area reservation request application; an area determination unit 2b that, when the area reservation request from the area reservation request application is accepted, determines whether or not the capacity of unallocated areas of a storage exceeds the required capacity specified by the area reservation request; an area release unit 2c that, when the capacity of unallocated areas of the storage does not exceed the required capacity, releases some of the unused areas from the allocated areas already allocated to applications that have had areas allocated thereto, as a free area; and an area allocation unit 2d that allocates the combined capacity of at least some of the unallocated areas and the freed area, as an allocated area corresponding to the area reservation request.SELECTED DRAWING: Figure 1
